Device for hooking/unhooking LC connectors

ABSTRACT

Device for hooking/unhooking connectors of the LC type, comprising a slide SL which, in order to unhook the LC connector, is pushed from the front side and presses a retaining latch of the LC connector.

TECHNICAL FIELD

[0001] The present invention relates to a device for hooking/unhooking connectors of the LC type.

[0002] This application is based on, and claims the benefit of, European Patent Application No. 03290423.7 filed on Feb. 21, 2003 which is incorporated by reference herein.

BACKGROUND OF THE INVENTION

[0003] In a number of situations there is a need for interconnecting electronic modules efficiently. For example in the new Telecom equipment design, there is an eavy use of known SFF (Small Form Factor) and SFP (Small Form Plugable) optical modules which can be interconnected on the front panel by LC optical connectors of a known type.

[0004] Typically the front panel width of said optical modules is small (i.e. 20 mm/25 mm). Therefore it is very difficult to hook/unhook (connect/disconnect) LC optical connectors manually by fingers.

[0005] In particular, with reference to FIG. 1, the LC connector has on a side a retaining latch engaging in a corresponding slot in the socket on the front panel of the optical module. To operate the LC connector manually a minimum width of the front panel should be required, which is greater than the available one. This is a drawback especially for removing/unhooking the LC connector, as it should be needed to press the retaining latch with the fingers.

[0006] This creates practical operating problems which render the LC optical connectors unusable with the available dimensions of the optical modules.

SUMMARY OF THE INVENTION

[0007] Therefore it is the main object of the present invention to provide a device for hooking/unhooking connectors of the LC type which solves the above mentioned problems.

[0008] This object is achieved by a device for hooking/unhooking at least one connector of the LC type, the connector to be inserted in a sockets placed in the front-panel of an electronic module and comprising a retaining latch for the engagement in the socket,

[0009] wherein said device comprises a slide with a “V” shaped protrusion placed in the front side of the module aside the socket, in such a position as by pushing the slide from the front side of the module, said “V” shaped protrusion pressing said retaining latch and the connector being unhooked.

[0010] The basic idea of the present invention is, in order to disconnect the LC connector, to provide a solution where pushing a slide from the front side, the connector retaining latch is pressed and the LC connector is unhooked.

[0011] These and further objects are achieved by means of an apparatus and method as described in the attached claims, which are considered an integral part of the present description.

BEST MODE OF CARRYING OUT THE INVENTION

[0012] The invention will become fully clear from the following detailed description, given by way of a mere exemplifying and non limiting example, to be read with reference to the attached drawing FIG. 1 wherein the device for hooking/unhooking connectors of the LC type is shown in front and side views.

[0013] As shown in FIG. 1, on the front panel FP of the electronic module there are sockets SK especially designed to host the LC connectors LC.

[0014] The LC connector has on a side a “V” shaped retaining latch LC-RL which engages in a corresponding slot in the socket SK, when inserted in the socket (see the side views REST and PUSH in the FIGURE).

[0015] According to the invention, an aperture guide (slot) is made close to the socket, where it is possible to thread a slide SL.

[0016] The front part of the slide SL comprises a “V” shaped protrusion VP towards the LC connector.

[0017] When the slide is in the rest position REST, the LC connector is inserted in the socket so as the “V” shaped retaining latch LC-RL engages in the socket SK.

[0018] By pushing the slide by fingers from the front side of the module, when the slide SL is in the push position PUSH at the end of its stroke, the “V” shaped protrusion VP of the slide SL presses the retaining latch LC-RL, which is released from the socket, and the LC connector is unhooked.

[0019] In the rear part of the slide SL, a spring (not shown in the FIGURE), connected to the slide and to the electronic module, pushes back the slide SL in the rest position REST when released by the fingers.

[0020] After the slide release, it is possible to remove the LC optical connector, catching its plastic strain relief.

[0021] Further implementation details will not be described, as the man skilled in the art is able to carry out the invention starting from the teaching of the above description.

[0022] Many changes, modifications, variations and other uses and applications of the subject invention will become apparent to those skilled in the art after considering the specification and the accompanying drawings which disclose preferred embodiments thereof. All such changes, modifications, variations and other uses and applications which do not depart from the spirit and scope of the invention are deemed to be covered by this invention.
